ABSTRACT:
A loading device for sequential loading of bars in machine tools comprises chutes (16) for arrival of a bar against stops (17) for stopping in a withdrawal position. Beyond the stops (17) there is a guide (20,20') for axial sliding of a bar in a direction aligned with the inlet of a machine tool (14). Raising elements (22) have their upper surface (23) inclined and terminating with a stop part (24) arranged substantially vertically to the guide (20,20'). Said raising elements (22) are mobile between a first position below the chutes (16) and the guides (20,20') and a second position above the stops (17) and the guides (20,20') in which they raise the bar placed in the withdrawal position to cause sliding onto the upper inclined surface (23) toward the guide ( 20,20') to a stop position (26). Upon return of the raising elements to the first position the bar in the stop position (26) is placed on the underlying guides (20,20') to be pushed by (pushers) (37,38) into the machine tool.
